The study identifies gut microbiome alterations in allergic rhinitis, suggesting a gut-nose axis that could inform new treatment approaches for this condition.

Scientists at Brigham and Women's Hospital and Harvard Medical School have developed a targeted genetic test to improve diagnosis for X-linked dystonia-parkinsonism (XDP), a rare and disabling movement disorder that affects primarily men of Filipino ancestry.

In patients of reproductive age who have cancer, fertility preservation for potential children in the future should be a high priority.

Physician responses to patient expectations can affect physician incomes and may help explain lower incomes for many women, racialized, and immigrant physicians, found a new study published in CMAJ.

Each year, thousands of stroke survivors are left with hemianopia, a condition that causes loss of half of their visual field (the "vertical midline"). Hemianopia severely affects daily activities such as reading, driving, or just walking through a crowded space.

LINTS, a non-masking low-intensity noise tuned to each patient’s tinnitus frequency, produced statistically significant but modest reductions in tinnitus burden in a phase II clinical trial. Improvements were confined to the treatment-only group, with high individual variability and strong dependence on precise acoustic fitting.

Whole mushroom consumption shows consistent benefits for cardiometabolic health, lowering triglycerides in self-chosen diets and improving fasting glucose in a single healthy dietary pattern trial. Early evidence also suggests increases in salivary IgA and possible blood pressure improvements, with no adverse biomarker effects reported.

Long-term aged garlic extract supplementation improved specific anxiety-related behaviors and enhanced memory and learning in aging mice. Proteomic profiling revealed extensive hippocampal and cortical molecular changes linked to synaptic signaling, neuroplasticity, and stress-response pathways.

The DASH diet supports metabolic health in people with diabetes by improving blood pressure, renal function, lipids, and modest glycemic markers while reducing risks linked to vascular and inflammatory pathways. Its broad nutrient-driven mechanisms also benefit related conditions such as neuropathy, PCOS, and retinopathy, making it a versatile tool for cardiometabolic care.

Pancreatic ductal adenocarcinoma is projected to become the second-leading cause of cancer death in the United States by 2030, according to the National Institutes of Health (NIH).

Chao-Yi Wu, PhD, OT, from the Department of Neurology and Edmarie Guzmán-Vélez, PhD, of the Department of Psychiatry at Mass General Brigham, are the lead and senior authors of a paper published in eClinicalMedicine, "Effects of Nicotinamide Riboside on NAD+ Levels, Cognition, and Symptom Recovery in Long-COVID: A Randomized Controlled Trial."

Counties in Pennsylvania that contained or were near cultivated cropland had significantly higher melanoma rates compared to other regions, according to a new study led by scientists at Penn State.

Since late 2021, a panzootic, or "a pandemic in animals," of highly pathogenic bird flu variant H5N1 has devastated wild birds, agriculture, and mammals.

A study out of the University of North Carolina at Chapel Hill has unveiled new insights into the inflammatory processes behind periodontitis, a common and debilitating gum disease. Research conducted by UNC Adams School of Dentistry's Julie Marchesan, DDS, PhD, and UNC School of Medicine's Jenny Y. Ting, PhD, found that a part of the immune system called the inflammasome plays a key role in disease development, and that blocking this system prevents bone resorption only in males.

Scientists at The Hospital for Sick Children (SickKids) have revealed a previously overlooked layer of genetic variation that could help explain why people experience disease differently, and why some treatments work better for certain populations.

Pregnancy loss may occur in as many as 25% of all pregnancies. Most of these losses occur in the first trimester, and about half are caused by genetic or chromosomal issues.

Certain serious fungal infections occur in regions of the United States with specific environments and are often tied to soil exposure.

This study analyzes how imaging is used to diagnose and manage Bell's palsy, a condition that causes sudden weakness in the muscles on one side of the face, usually temporarily.

Metabolic dysfunction-associated fatty liver disease (MAFLD) has emerged as a predominant chronic liver condition globally, intricately linked with obesity, type 2 diabetes (T2DM), and metabolic syndrome.

The Terasaki Institute for Biomedical Innovation (TIBI) is pleased to announce its collaboration with the California Institute of Technology (Caltech) on a newly awarded $2.8 million Discovery Stage Research (DISC0) grant from the California Institute for Regenerative Medicine (CIRM).
